ROBERT J. RENNIE, OF MOOERS FORKS, NEW YORK, ASSIGNOR OF ONE-HALF TOWILLIAM F. KENNEDY, 0F CHAMPLAIN, NEW YORK.

CAR-DOOR FASTENER.

Application filed February 20, 1911.

To all whom it may concern:

Be it known that 1, ROBERT J. RENNIE, a citizen of the United States,residing at Mooers Forks, in the county of Clinton and State of NewYork, have invented a new and useful Car-Door Fastener, of which thefollowing is a specification.

One object of the invention is to provide novel means for looking to acar, a door which is mounted thereon for longitudinal sliding movementand for transverse swinging movement.

Another object of the invention is to provide novel means for operatingthe locking bolts of a car door, and to provide a device whereby saidmeans may be held in fixed position with respect to the car.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in thepreciseembodiment of invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings,Figure 1 shows in side elevation, a portion of a carequipped with the device of my invention; Fig. 2 is a verticaltransverse section of the structure shown in Fig. 1; Fig. 3 is anenlarged vertical section showing the locking bolt and the car-carriedmeans with which the bolt engages, to hold the car door in fixedrelation with respect to the car; parts being shown in elevation.

In the drawings, the numeral 1 denotes the side wall of a car, thenumeral 2 denoting the door of the car.

Secured to the car door 2, intermediate the upper and lower endsthereof, and adjacent the outer, lateral edges of the car door, arebearing 16, in which is journaled for rotation, a shaft 17, provided,intermediate the bearings 16, with cranks 20. At one end, the shaft 1 1protrudes beyond one of the bearings 16, so as to overlap the side wall1 of the car. This end of the shaft 1.7 is provided with a lever 18,having an opening, through which protrudes a staple 19, inserted intothe side wall 1 of the car. Through this staple 19 may be inserted aseal, a padlock or the like, the construction being such, obviously,that when the seal or Specification of Letters Patent.

Serial No. 609,747.

padlock is in place, the lever 18 will be held in approximately parallelrelation to the side wall of the car, rotation of the shaft 17 beingthereby prevented. The cranks 2O carry depending pitmen 21, pivoted, asshown at 22, to the upper ends of locking bolts 23, mounted forlongitudinal reciprocation beneath guides 24, secured by means of bolts25 or the like, to the car door 2, adjacent the lower edge thereof.These bolts 23 are beveled as shown at 26 on their outer faces, andadjacent their lower ends, for a purpose to be described hereinafter.

The locking bolts 23 are adapted to engage the keepers, secured to theside wall 1 of the car below the lower edge of the door 2, the keepersbeing denoted generally by the reference character 27. Each keeperconsists of a base plate 28, secured by means of bolts 29 or the like,to the side wall 1 of the ear, the base plate 28 being equipped withoutstanding ribs 30, connected adjacent their upper ends by a transversestrap 31, inclined, as clearly seen in Fig. 3, to receive the beveledend 26 of the locking bolt 23, the construction being such that when thebeveled end of the locking bolt is thrust downwardly behind the strap31, the car door 2 will be forced inwardly at its lower end, into close,intimate contact with the side wall 1 of the car, thereby efl'ecting aperfect closure. Between the ribs 30, the base plate 28 is cut away atits lower edge, as shown at 33, the keeper being open beneath the lowerend of the locking bolt 23, as shown at 32, the construction being suchthat should any material accumulate behind the strap 31, suchaccumulated material will not lodge within the keeper, to interfere witha proper seating of the looking bolt 23 within the keeper.

A pair of the keepers 27 are located directly beneath the doorway of thecar, the construction being such that when the looking bolts 23 areengaged with the keepers, the door 2 of the car will be held across thedoorway, thereby effecting a closure of the same. However, otherkeepers, similar to the keepers 27, and denoted specifically by thenumeral 34 in Fig. 1, may be positioned to one side of the doorway ofthe car, so that the door may be locked in open position, withoutclosing the doorway. It will be understood that these keepers 34 may bemultiplied to any desired extent, so that the door may be lockedsuccessively, in a number of difierent opened positions.

Presupposing that the parts are positioned in Figs. 1 and 2-, theoperation of the device is as follows. The seal (not shown) is removedfrom the staple 19, whereupon the free end ofthe lever 18 may be swungout wardly, away from the side wall 1 of the car, this movement of thelever 18 imparting a rotation to the shaft 17, the cranks 20 of which,through the instrumentality of the pitmen 21, will elevate the lockingbolts 23, withdrawing their lower ends from -beneath the straps 31 ofthe keepers 27,

whereupon the car door 2 may be swung outwardly at right angles to theside wall 1 of the car; or, if desired, the car door, obviously, may beslid parallel to the side wall 1 of the car, so as to disclose thedoorway therein. WVhen it is desired to lock the car door, throughengagement with the keepers 27 or through engagement wit-h the keepers34, the free end of the lever 18 may be swung downwardly, rotating theshaft 17,

and forcing the locking bolts 23 into en gagement with the keepers 27 or34, as may be, the inclined strap 34 and the beveled ends 26 of thelocking bolts 23, cooperating to force the car door 2 against the sidewall 1 of the car.

From the foregoing it will be seen that the lower end of the car doormay readily be swung outwardly, to permit grain or the like, to flow outof the car. The device, however, in no wise interferes with the slidingmovement of the car door 2, in the usual manner. VVhet-her the car doorhe in open position or in closed posit-ion, the door may be lockedreadily against movement, by manipulating the lever 18.

It is to be noted that the staple 19 exercises the double function of adetent, for

which the shaft 17 is journaled for rota-- tion, serves to reinforce thedoor 2 in that portion of the door which is engaged by the staple 19,when the door 2 is slid. Owing to the fact that the locking lever 18engages directly with the car, and not with the door 2, the door may beheld in closed posit-ion, temporarily, by the lever 18 and the staple19, even though the locking bolts 25 and keepers 27 be broken.

Having thus described the invention, what is claimed is The combinationwith a car having a doorway, and a vertically swinging, sliding door, ofa projection upon the car, at one side of the doorway, the projectionbeing engageable by the door, to aline the door approximately with thedoorway, when the door is slid, the projection having an opening adaptedto receive locking means, bearings upon the door adjacent its edges, onebearing being opposite the projection, to reinforce the door and at itspoint of engagement with the projection; a shaft journaled for rotationin the bearings; a lever upon one end of the shaft, having an open-- ingadapted to receive the projection, thereby to hold the shaft againstrotation; a bolt slidable upon the door; means upon the car to receivethe bolt; and an operative connection between the bolt and the shaft.

In testimony that I claim the foregoing as my own, I have hereto atfixedmy signature in the presence of two witnesses.
